The easiest way to see the sights around Xi`an is either to join an organized tour or to take the excellent (and cheap!) Sightseeing Bus tour. These buses leave from the railway station in Xi'an at regular intervals throughout the day. Riders purchase one ticket which allows them to hop on and off as many of the buses as they choose in one day. Buses pass through the major sites approximately every ten minutes and this is a great way to see the sites at your own pace. The Eastern trip can be done in one day, the Western trip is further so allow a long day for this one! Their customer service line are (029)86243067 and (029)-86268494.
